Andreaa, picked us up early and asked what we had already seen in the park. Also inquired about what we would like to see and planned our day accordingly. We made several stops, which included hiking to some spectacular waterfalls. Also took Slough Creek Campground Rd., to view numerous herds of Bison. Many were on the road or directly to the sides of the road and we were able to stop and watch them grazing. I was not expecting to hear the grunting noises the males are constantly making. We then located a Bison carcass from the day before and saw several bald eagles feeding. We also saw a Sandhill Crane, about 50 yards off the road. We stopped for lunch near a shaded and picturesque stream. We made numerous stops on our return trip to Old Faithful Inn, to finish out our day.. Andreaa, was very efficient with our time, but we never felt rushed. He even included heathy snacks and drinks to keep us hydrated. He attended to our every need. We would highly recommend Yellowstone Adventure Tours and Andreaa, a wonderful and knowledge guide. It was well worth our time. We had an amazing day and learned so much! Thanks so much, Andreaa!
